Description

Automotive air conditioners have different working modes, and the internal space of the air conditioner is limited, which has a great impact on performance indicators such as the air volume and temperature linearity in various modes.

[0003] The air volume is the magnitude of the wind force that the automotive air conditioner can provide for the entire passenger compartment. For example, whether it can quickly heat in winter and quickly cool in summer is closely related to the air volume. Temperature linearity is the temperature performance of each air outlet in the passenger compartment in different modes. For example, the temperature of the defrost air outlet will affect the defogging and defrosting of the glass, thereby affecting the safety of the passengers in the car, and the temperature of the face-blowing air outlet will directly affect the comfort of the passengers.

[0004] An air guide cylinder is usually arranged inside the automotive air conditioner to adjust the temperature linearity, but the setting of the air guide cylinder will increase the wind resistance of the automotive air conditioner, thereby reducing the air volume. At present, multiple air guide cylinders are arranged inside the automotive air conditioner in the prior art, and all the air guide cylinders are fixed, which causes the current structure of the automotive air conditioner to be unable to balance the two indicators of temperature linearity and air volume, thus reducing the passenger experience.

[0045] This embodiment provides an automotive air conditioner that can simultaneously take into account two performance indicators, namely temperature linearity and air volume, and improve the experience of passengers.

[0046] Such as Figures 1-3As shown in the figure, the automotive air conditioner mainly includes a first housing 100, a second housing 200, a flow guide cylinder 300, a movable connecting rod 400, and a drive assembly (not shown in the figure). Among them, an air conditioner core 110 is built into the first housing 100. The second housing 200 is communicated with the first housing 100, and a plurality of air outlets are provided on the second housing 200. One end of the movable connecting rod 400 is connected with a rotating shaft (not shown in the figure), and the rotating shaft is arranged through the flow guide cylinder 300 and the first housing 100, so that the flow guide cylinder 300 is movably connected with the first housing 100; the other end of the movable connecting rod 400 is connected with an air door plate 500, and the air door plate 500 is located in one of the air outlets. The drive assembly is drivingly connected with the air door plate 500, so that the air door plate 500 can drive the movable connecting rod 400 to move, and the movable connecting rod 400 drives the flow guide cylinder 300 to move.

[0047] Based on the above design, during the actual use of the automotive air conditioner, the drive assembly can drive the air door plate 500 to move, and then the air door plate 500 can drive the movable connecting rod 400 to move. The movable connecting rod 400 drives the flow guide cylinder 300 to rotate around the rotating shaft, so that the flow guide cylinder 300 can face one of the air outlets or between any two air outlets. In this way, a certain amount of air volume can flow out of the corresponding air outlets in different working modes of the automotive air conditioner. At the same time, the structure of the flow guide cylinder 300 in this embodiment is simple, and the flow guide cylinder 300 is a simple hollow cylindrical shape, which avoids the resistance to the air flow 10 caused by the complex structure of the flow guide cylinder 300 in the traditional technology and ensures the smooth movement of the air flow 10; at the same time, since the flow guide cylinder 300 can change its actual position in different working modes, the flow guide cylinder 300 can linearly adjust the temperature of the air flow 10 in different modes, thereby improving the experience of passengers.

[0048] It should be noted that the principle of linearly adjusting the temperature of the air flow 10 by the flow guide cylinder 300 in this embodiment belongs to the prior art in this field. The flow field diagram of the air flow 10 can be simulated by using the simulation software of finite element analysis on the market, and it will not be elaborated in detail here.

[0049] Compared with the prior art, in this embodiment, through the settings of the drive assembly, the air door plate 500, the movable connecting rod 400, the flow guide cylinder 300, and the rotating shaft, the flow guide cylinder 300 can rotate with different working modes of the automotive air conditioner, and then adjust the position of the flow guide cylinder 300, so that the flow guide cylinder 300 can adjust the direction of the air flow 10, reduce wind resistance, and increase the air volume; at the same time, the structure of the flow guide cylinder 300 is simple, and through the setting of the flow guide cylinder 300, the temperature of the air flow 10 can be linearly adjusted in different working modes, thereby improving the experience of passengers.

[0050] In addition, the automotive air conditioner in this embodiment can reduce noise. Specifically, by setting the flow guide cylinder 300 to be rotatable, the air flow 10 in different working modes can move stably and smoothly, reducing the risk of vortex oscillation generated in the second housing 200, thereby reducing the noise risk.

[0051] Optionally, the movable link 400 in this embodiment has multiple degrees of freedom. For example, the movable link 400 has three degrees of freedom, four degrees of freedom, five degrees of freedom, etc., which can improve the flexibility and reliability of the movable link 400 driving the flow guide cylinder 300 to rotate, and improve work efficiency.

[0052] Optionally, the connection mode between the air door plate 500 and the movable link 400 in this embodiment can be threaded connection, welded connection, snap connection, etc.

[0053] As Figures 1-3 shown, in this embodiment, a first arc surface 310 is provided on the flow guide cylinder 300, and a second arc surface 230 is provided on the second housing 200. The first arc surface 310 is adapted to the second arc surface 230. Through the setting of the first arc surface 310 and the second arc surface 230, the smoothness and reliability of the movement of the flow guide cylinder 300 can be improved, the movement track of the flow guide cylinder 300 can be fixed, and the phenomenon of the flow guide cylinder 300 shaking unstably can be avoided.

[0054] As Figures 1-3 shown, in this embodiment, the air outlet includes a face blowing air outlet 210 and a defrosting air outlet 220. The air door plate 500 is located in the defrosting air outlet 220. The automotive air conditioner has a first working mode, a second working mode, and a third working mode.

[0055] When the automotive air conditioner is in the first working mode, the flow guide cylinder 300 is facing the face blowing air outlet 210, and the air door plate 500 blocks the defrosting air outlet 220. At this time, the flow guide cylinder 300 can divert most of the air flow 10 blown out by the air conditioning core 110 to the face blowing air outlet 210, ensuring the stable air volume of the face blowing air outlet 210 and reducing the air resistance. Since the air door plate 500 blocks the defrosting air outlet 220, there is no air flow 10 flowing out of the defrosting air outlet 220 at this time.

[0056] When the automotive air conditioner is in the second working mode, the air guide cylinder 300 is located between the face-blowing air outlet 210 and the defrosting air outlet 220. The air door plate 500 opens the defrosting air outlet 220, and the air door plate 500 is arranged at an acute angle with the inner wall of the defrosting air outlet 220. Specifically, in the second working mode, there is a demand for air flow 10 at both the face-blowing air outlet 210 and the defrosting air outlet 220. When switching the mode, the drive assembly rotates the air door plate 500 to a half-open position. At this time, the air door plate 500 is arranged at an acute angle with the inner wall of the defrosting air outlet 220, and the movable connecting rod 400 drives the air guide cylinder 300 to rotate to the middle position (i.e., between the face-blowing air outlet 210 and the defrosting air outlet 220). The air flow 10 can be divided into two beams through the air guide cylinder 300 and flow out from the face-blowing air outlet 210 and the defrosting air outlet 220 respectively, with smooth flow, and the temperatures of the face-blowing air outlet 210 and the defrosting air outlet 220 are ensured to be reasonable.

[0057] When the automotive air conditioner is in the third working mode, the air guide cylinder 300 faces the defrosting air outlet 220. The air door plate 500 opens the defrosting air outlet 220, and the air door plate 500 is parallel to the inner wall of the defrosting air outlet 220. Specifically, when the automotive air conditioner switches the mode, the drive assembly rotates the air door plate 500 to the fully open position. At this time, the air door plate 500 is parallel to the inner wall of the defrosting air outlet 220, and the movable connecting rod 400 drives the air guide cylinder 300 to rotate towards the defrosting air outlet 220. The air flow 10 generated by the air conditioning core 110 flows out from the defrosting air outlet 220 after passing through the air guide cylinder 300. While maintaining the smoothness of the air flow 10, the temperature linearity requirement of the third working mode is satisfied.

[0058] It should be noted that a rotating air door is provided at the end of the face-blowing air outlet 210 facing the passenger in the third working mode. In the third working mode, the passenger can manually rotate the above rotating air door, thereby achieving the purpose of blocking the face-blowing air outlet 210 by the rotating air door and avoiding a small amount of air flow 10 from flowing out of the face-blowing air outlet 210.

[0059] Optionally, the air flow 10 generated by the air conditioning core 110 in this embodiment can be cold air or warm air.

[0060] Optionally, in some embodiments, a sealing ring is provided on the circumferential edge of the air door plate 500, and the sealing ring can abut against the inner wall of the defrosting air outlet 220. By providing the sealing ring, the sealing performance of the air door plate 500 for blocking the defrosting air outlet 220 can be improved, and the phenomenon of the air flow 10 flowing out of the defrosting air outlet 220 in the first working mode can be reduced or avoided.

[0061] Such as Figure 2As shown in the figure, a flow guiding portion 240 is provided on the second housing 200 in this embodiment. The flow guiding portion 240 is located between the face blowing air outlet 210 and the defrosting air outlet 220. When the automotive air conditioner is in the second working mode, the flow guiding cylinder 300 is directly opposite to the flow guiding portion 240. The provision of the flow guiding portion 240 can improve the guiding effect on the air flow 10, so that in the second working mode, the air flow 10 can flow through both the face blowing air outlet 210 and the defrosting air outlet 220, improving the working efficiency.

[0062] It can be understood that through holes are provided on the first housing 100 in this embodiment. The through holes are communicated with the flow guiding cylinder 300, so that the air flow 10 generated by the air conditioning core 110 can move to the flow guiding cylinder 300. The number and shape of the through holes are not limited in this embodiment.

[0063] Optionally, the drive assembly in this embodiment can be set as a motor. The motor is drivingly connected to the air door plate 500, so that the motor can drive the air door plate 500 to move, and further the air door plate 500 can drive the movable connecting rod 400 to move, saving costs.

[0064] Optionally, the first housing 100 and the second housing 200 in this embodiment are integrally formed or welded. The first housing 100 and the second housing 200 can both be made of engineering plastic material or both be made of metal material.

[0065] This embodiment also provides an automobile, which includes the above-mentioned automotive air conditioner.

[0066] Since this automobile has the above-mentioned automotive air conditioner, the automotive air conditioner of this automobile can simultaneously take into account the performance of temperature linearity and air volume, reduce the wind resistance, optimize the temperature linearity, and improve the passenger experience.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments here.
